To render the second wave of suburbanization which took place after 2002 (Ouředníček,
Posová 2006), it will be necessary to wait for the release of an updated database CLC 2006.
With respect to the above mentioned facts, it is possible to state analyses of changes in
urban
areas included in the CLC database by several methods:
1. increase in urban area expressed in administrative units (Bičík & Kupková, 2006;
Hasse & Lathrop, 2003)
2. increase in urban area expressed in reference to a regular net (Poudevigne, 1997)
3. assessment of a change in urban areas by means of suitable indicators in certain
spatial units (kol. 2006)
Information on localization and a process range is crucial to an impact assessment; in
addition, it provides us with information where this transformation happens.
Methodology
The aim of this paper was to map a spatial pattern of the first wave of suburbanization in
the Czech Republic. For comparison, the approach assessing a change in terms of
administrative units as well as the approach of assessing a change in a regular net was used.
Data on categories of urban areas were exported from the CORINE Land Cover database
from the years 1990 and 2000 and these categories were consequently configurated into the
categories
rendering commercial and residential sub/urbanization. In the first category the
continuous and discontinuous urban house-building was involved (codes 111,112 of the
CLC nomenclature); and the second category contains industrial or commercial zones,
public road and railway systems with neighbouring areas, airports, sport and recreational
facilities (codes 121,122,124,142 of the CLC nomenclature). As a reference base of
municipal boundaries the layer from ARC ČR 500 was used and a net mesh-sized 1km
ar
2 was
created for assessment in a regular net. Areas of two tracked categories were calculated for
single municipalities and meshes and these were expressed relatively in reference to a unit
ea in per cent. The data were analysed and the results visualised by the help of ArcGIS
9.2 tools.

cation of new constructed premises became a significant factor. In both cases the most
significant increase in suburban areas was noticed in the rear of Prague where this process
was also the most frequently examined and described. The first wave of residential
suburbanization became also evident together with the outskirts of Prague in its southern
surroundings with attractive landscape; the synonyms of this development were the
municipalities of Jesenice, Průhonice or Dobřejovice. Significant changes in construction
area were also noticed p.e. in the land registrers in Hostivice, Rudná, Řitka, Líbeznice,
Šestajovice and in a number of others all over the Prague territory. Such significant changes
– an increase in residential areas over 15% - have not happened in the rear of any other big
cities. But the process of sub/urbanization have not been naturally avoided on the outskirts
and surroundings of Brno, Ostrava, Plzeň and České Budějovice, nevertheless it did not
